The Boxster/Cayman platform has a tendency to overwork and overheat the Power Steering pump to the point that some of the lines have been known to melt!

Cars that are Autocrossed or Tracked suffer the most from this malady.

One of the simplest and most effective solutions is to install a smaller crankshaft pulley known as an under-drive pulley, because it under-drives the secondary systems (A/C, Alternator and Power Steering).

There are no negative issues with cooling, charging or steering, but there’s an upside: the engine will get back about 5-7 HP!

This is a precision-engineered pulley which aligns correctly with the other sub systems’ pulleys to eliminate excessive belt wear.
